摘　　要：针对Net Simulator(NS)仿真工具用于无线Mesh网(Wireless Mesh Network,WMN)的不足,提出简化的WMN链路多速率冲突和干扰模型,建立最大干扰节点数评估和干扰概率的计算方法,最终为NS2.26增加实用的远程节点干扰模拟机制。仿真试验验证该机制可有效模拟WMN链路特征。According to the shortages when adopting Net Simulator （NS） Toolkit for simulating Wireless Mesh Network （WMN）, an applied simulation schemes for Distant Terminal Interfere of Wireless Mesh Network as a patch for NS2.26 was proposed by adopting a simplified model of multirate contention and interference. The methods to evaluate maximum number of interference nodes and to calculate interference probability of distant terminal were proposed. Simulation results demonstrate the proposed mechanism can simultaneously adapt to the features of WMN links.
